**Beyoncé’**s personal assistant, Sam Greenberg, has quite the job—and she’s always, ahem, “On The Run” with days that vary from skydiving with Queen B in New Zealand to accompanying the superstar on the Grammys red carpet. Much of the job may be adjacent to the limelight, but Greenberg keeps her work uniform centered on pared-back basics ranging from rompers to overalls. As for one of the biggest challenges? How to haul all of those chic pieces along for the ride. From staples to suitcases, see how Greenberg’s style plays into her life assisting the chart-topping style icon and business mogul.

Quality ControlI believe heavily in the quality of the clothes that you purchase—good materials are important to me. I try to take pride in things I wear. I also think it is important to wear designers like Proenza Schouler and Balenciaga in a way that is super functional. Do not be afraid to walk in something and don’t worry that it may get ruined, just wear it for what it is. You can wear it with a pair of sneakers to make it functional but also really fashionable.

Comfort FirstI definitely don’t wear heels most of the time, because I’m always on my feet and running around. I try to stick to really cool flats and sneakers. I’m a big fan of Common Projects right now. I have about four pairs of those that I rotate. I also have a Stella McCartney platform that she is selling this season. They are my new favorites because they give me a little height but I can still run and walk around in them. Especially being in New York City, it’s nice to have something comfortable.

When It Comes to Packing, Less Is Always MoreI showed up my first day of the job ready to go on tour with two huge suitcases, a small wheel carry-on, a carry-on for my shoulder, and my purse. I soon learned that was not going to be an effective way to travel, and ended up cutting it down.

I pack up one to two suitcases and drag those around with me everywhere I go, and then I bring a carry-on with me. If I have a smaller trip I just throw stuff in there so I can run out. Basically, I am always ready to travel: so I have a bag already packed and ready-to-go.

I’m not really good at unpacking, so I kind of leave it half-empty, half-full in case of a last-minute type scenario. I hang up everything that needs to be hung so it doesn’t get wrinkled but usually T-shirts, jeans, and things like that are always tossed in my bag.

What to Carry On the RunI’ve gone through a number of different suitcases over the past two-and-a-half years. I’ve done Tumi, but my suitcase now is from when I went to camp because it is the biggest duffel I could find! I had one of those big Balenciaga overnight bags that I beat to death. Then I moved onto the Proenza Schouler PS 1 but the big version so I can stuff a bunch of stuff in there. Every bag that I carry without wheels has to have a large shoulder strap so I can throw it over my shoulder and run.

The Art of FoldingMy mom is a professional packer so I was lucky enough to learn from her. It is all about how you fold something. I wrap a lot of things in plastic so they don’t wrinkle in my suitcase because they usually sit in there for a long time. Shoes always go at the bottom. Make everything as small as you can, and as flat as you can—and also always leave room because you never know what you are going to pick up on the road.

Work to Play and Back AgainI wear something that is comfortable and that can easily transition into work. Sometimes we get off the plane and go straight to a show or to a meeting. I always make sure it isn’t “too sweatpants and sweatshirt.” I wear overalls [by Topshop], which are really comfortable on planes. I definitely wear flats—Chanel espadrilles have been my favorite things for the past two years—they are like bedroom slippers, but look good with a lot of things. I also have some great Balenciaga jackets because they dress up what I could be wearing in case I need to run out somewhere nicer. I have the “Join A Weird Trip" Balenciaga jacket and it makes things look a little bit cooler.

Back to BlackIf I’m on tour, I’m absolutely wearing black backstage. I’ve always worn black, so it wasn’t too much of a challenge. It’s to blend into the background; people won’t have to see a person in a bright pink top running back and forth on stage. And if there are times I have to go out in the crowd during a performance, I don’t want to be noticed. If it is a summer tour, I have two or three black rompers that I live in. If it is winter tours, I wear jeans, sneakers, and sometimes even some Beyoncé merchandise because that is usually black too, so that is helpful to blend in.

Good Merchandise Makes Everything EasierThe pieces are curated so well and they are designed in such a cool way. Whether it is throwing on a sweatshirt that says “Surfboard” to go to the gym or putting on one of the T-shirts under a Levi’s denim jacket, it's really functional and cool—you don’t feel like you are walking around with a big Beyoncé face on you! You have some cool nod to her that everyone understands, but is also really chic as well.

It’s Not About Standing OutI try to blend in the background as much as possible. Being on the red carpet is the most glamorous, but for me, like for the Grammys this year, I wore a pair of black jeans and a black tank top and then I put on my Stuart Weitzman thigh-high Highland boots. They [the shoes] make my outfit a little bit nicer, but still comfortable and functional.

Wherever Beyoncé Is, Great Clothes Will FollowWe jumped off the New Zealand Sky Tower and I had a really cute blue onesie on. When I was on the shoot for “On The Run,” we shot a whole bunch of footage for the actual show and we were in the desert and it was really cold, even in the middle of Los Angeles. I snuck into the wardrobe trailer and pulled out a big fur and threw that on. It is always fun to play dress-up, because on shoots especially there are always great things.

It’s All About Who You Work ForI think that in this job it is about looking clean and looking cool, and not trying to be much in the spotlight because that isn’t why you’re there. It is also representing whom you work for. For me, the fun of it is walking in and seeing that B’s stylist has pulled something from what I have or vice versa. It is a cool experience to learn from her and curate my taste along with hers because she is quite the style icon.
